Abstract
We report Afroapseudes cretacicus n. gen., n. sp. (Tanaidacea Dana, 1849; Apseudomorpha Sieg, 1980) from the Upper Cretaceous (Cenomanian-Turonian) of the Gara Sbaa layers (southeastern Morocco). The new species is considered as a possible lineage between the Jurassic and the more recent Paleogene Apseudomorpha, partially covering the wide gap of tanaidacean fossil records between Mesozoic and Cenozoic forms. At the same time, this results to be the first fossil record of a tanaidacean from Africa, enlarging the scarce knowledge on the real diversity and distribution of this poorly reported crustacean group during the geological times.
期刊介绍：
The Boletín de la Sociedad Geológica Mexicana is a completely free-access electronic journal published semi-annually that publishes papers and technical notes with its main objective to contribute to an understanding of the geology of Mexico, of its neighbor areas, and of geologically similar areas anywhere on Earth’s crust. Geology has no boundaries so we may publish papers on any area of knowledge that is interesting to our readers.
We also favor the publication of papers on relatively unfamiliar subjects and objectives in mainstream journals, e.g., papers devoted to new methodologies or their improvement, and areas of knowledge that in the past had relatively little attention paid them in Mexican journals, such as urban geology, water management, environmental geology, and ore deposits, among others. Mexico is a land of volcanos, earthquakes, vast resources in minerals and petroleum, and a shortage of water. Consequently, these topics should certainly be of major interest to our readers, our Society, and society in general. Furthermore, the Boletín has been published since 1904; that makes it one of the oldest scientific journals currently active in Mexico and, most notably, its entire contents, from the first issue on, are available online.
